The AROS project has published a year-in-review item... In July. But alas. "Once again, the news has been long delayed, mainly because we've been too busy adding features and fixes to AROS. In fact, so much has happened in the last year that what follows is only a selection of highlights."

I think the main points recently are 680x0 Amiga support (getting close to no longer needing the original Amiga roms), and wireless network support. The second point is probably more important to many people, but the first means being able to run legacy apps and games under emulation without copyrighted rom images.
